Description

Technical Field

[0002] Carbonization-modified recycled coarse aggregate is a material that is processed to improve the performance of recycled coarse aggregate. Recycled coarse aggregate is the aggregate obtained by crushing, screening and other processes of discarded concrete, bricks and stones or industrial waste. Carbonation modification uses carbon dioxide to react chemically with alkaline substances on the surface and inside of the recycled coarse aggregate to generate carbonates such as calcium carbonate. On the one hand, calcium carbonate precipitation can fill the pores and microcracks of the aggregate, reduce the porosity and increase the density of the aggregate. On the other hand, the carbonization reaction can improve the properties of the aggregate surface and enhance the interfacial bonding performance between the aggregate and the cement paste. The recycled coarse aggregate is placed in a gas environment containing a certain concentration of carbon dioxide and carbonization treatment is carried out under normal pressure and certain temperature conditions.

[0003] When using the existing carbonized modified recycled coarse aggregate preparation device, according to actual production needs, if the recycled coarse aggregate of different materials is replaced for carbonization modification treatment, the internal cleaning of the preparation device needs to be carried out in time. This is because the recycled coarse aggregates of different materials may contain different impurities. If the inner wall of the equipment is not cleaned, the impurities remaining from the previous treatment may be mixed into the new recycled coarse aggregate, affecting the purity and performance of the new product. In the existing technology, most of them do not have a mechanism for timely cleaning, which in turn affects production efficiency.

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] like Figure 1-14As shown, a highly efficient carbonized modified recycled coarse aggregate preparation device comprises a box body 1, a feed port opened at the top of the box body 1 and a discharge port opened at the bottom of the box body 1, a rotating column 2 is rotatably connected to the top of the box body 1, a horizontal column 3 is fixedly connected to the surface of the rotating column 2, a plurality of stirring columns 4 are fixedly connected to the surface of the rotating column 2 below the horizontal column 3, connecting channels 5 are opened inside the rotating column 2 and inside the plurality of stirring columns 4, through holes 6 are equidistantly opened on the surface of the stirring columns 4, a first nozzle is fixedly connected to the wall of the through hole 6, a scraper 7 is symmetrically rotatably connected to the inner wall of the box body 1, and the horizontal column 3 is slidably connected to the two scrapers 7;

[0037] An arc-shaped groove 9 is provided on the surface of the box body 1, and one end of the groove wall of the arc-shaped groove 9 is rotatably connected to an arc block 10. A first annular groove 11 is provided on the inner wall of the box body 1. There are two first annular grooves 11, which are communicated with the arc-shaped groove 9. The groove wall of the first annular groove 11 is rotatably connected to a rotating ring 12. A movable block 13 is installed on the inner side of the rotating ring 12. The arc block 10 is fixedly connected to the outer side of the rotating ring 12. A second nozzle 14 is fixedly connected to the surface of the rotating ring 12. A connecting hole 15 is provided on the inner wall of the box body 1. The side wall of the arc block 10 is symmetrically fixedly connected to the limiting column 16. The four limiting columns 16 are all rotatably connected to the box body 1. The outer side of the limiting column 16 is sleeved with a first spring, and the surface of the arc block 10 away from the rotating ring 12 is fixedly connected with a convex column 17;

[0038] The surfaces of the two second nozzles 14 away from the interior of the box body 1 are fixedly connected to a first connecting pipe 18, a second connecting pipe 19 is fixedly connected below the first connecting pipe 18, and one end of the second connecting pipe 19 away from the first connecting pipe 18 is fixedly connected to a water tank 20, which is fixedly connected to the box body 1, and a vertical column 21 is slidably connected to the side of the water tank 20 close to the box body 1, a rotating plate 22 is installed on the surface of the vertical column 21 through a torsion spring, and a first rack 23 is fixedly connected to one end of the vertical column 21 near the top, a first gear 24 is meshed with the surface of the first rack 23, and a second gear 25 is meshed with the outer side of the first gear 24, and an adjusting mechanism 26 for adjusting the water outflow from the water tank 20 to clean the inner wall of the box body 1 is provided below the second gear 25;

[0039] It should be noted that the second connecting pipe 19 is a corrugated pipe; multiple second nozzles 14 can be set according to actual usage. When the second nozzles 14 cooperate with the connecting holes 15, they can spray water at the same time to clean the surfaces of the stirring column 4, the rotating column 2 and the scraper 7 to ensure the cleaning effect.

[0040] The upper end surface of the scraper 7 is provided with a connecting groove 71, and the lower side of the horizontal column 3 is symmetrically fixedly connected with a connecting column, which is slidably plugged into the connecting groove 71;

[0041] It should be noted that the arrangement of the connecting groove 71 and the connecting column can still drive the scraper 7 to rotate when the rotating column 2 is adjusted to move upward.

[0042] The inner side of the rotating ring 12 is symmetrically fixedly connected to the limit bar 121, and the two limit bars 121 are both rotatably connected to the box body 1. A groove 122 is opened on the inner side of the limit bar 121, and the groove wall of the groove 122 is symmetrically fixedly connected to the positioning column 123. The outer side of the positioning column 123 is provided with a return spring. The ends of the two positioning columns 123 away from the groove wall of the groove 122 are both slidably connected to the movable block 13. One end of the two return springs is fixedly connected to the groove wall of the groove 122, and the other end of the two return springs is fixedly connected to the movable block 13.

[0043] It should be noted that after the first motor is started, the fifth gear 29, the fourth gear 28, the third gear 27 and the rotating column 2 drive the horizontal column 3 to rotate, and then drive the scraper 7 to rotate. The scraper 7 can contact the movable block 13, drive the movable block 13 to move, and the rotating ring 12 rotates as the movable block 13 moves. The first spring is compressed until the convex part of the surface of the rotating ring 12 near the first connecting pipe 18 can contact the wall of the arc groove 9. At this time, the second nozzle 14 is separated from the connecting hole 15. As the scraper 7 and the rotating column 2 continue to rotate, the second nozzle 14 is separated from the connecting hole 15. During the mixing of the recycled coarse aggregate in the mixing tank, the movable block 13 will not return to its initial position due to the elastic force of the first spring. According to the actual production situation, before the recycled coarse aggregate of different materials is replaced for carbonization modification, after the first motor is turned off, the rotating column 2, the horizontal column 3 and the scraper 7 can continue to rotate, and the speed gradually decreases. Under the elastic force of the first spring, the protruding column 17 can contact the rotating plate 22, driving the rotating plate 22 to move in the direction of compressing the second spring, thereby being able to discharge water from the water tank 20 and pass through the second connecting pipe 19 and the first connecting pipe 18. , sprayed through the second nozzle 14. During this process, the scraper 7 will contact the movable block 13 many times. When the scraper 7 is not in contact with the movable block 13, the water sprayed by the second nozzle 14 can clean the surface of the rotating column 2, the stirring column 4 and the scraper 7. The scraper 7 will drive the movable contact and drive the rotating ring 12 to rotate until the convex part of the surface of the rotating ring 12 near the first connecting pipe 18 contacts the wall of the arc groove 9 again, and relative rotation occurs between the movable block 13 and the scraper 7. The reset spring is compressed, slowing down the rotation speed of the scraper 7 and the rotating column 2, that is, the convex column 17 It will be adjusted and moved to one end of the arc groove 9 many times. Under the action of the second spring force, the first rack 23 will also return to its initial position. Then, under the action of the first spring force, the boss 17 will drive the rotating plate 22 to move again, so that the water in the water tank 20 can pass through the second connecting pipe 19 and the first connecting pipe 18 many times and be sprayed out by the second nozzle 14, thereby ensuring the cleaning effect. There is no need to set up an additional conveying mechanism for water transportation. After the cleaning is completed, the recycled coarse aggregate of different materials can be quickly replaced for carbonization modification, which can further improve the preparation efficiency.

[0044] The outer side of the fifth gear 29 is meshed with the outer side of the cylinder 203, and the first motor is fixedly connected to the top of the cylinder 201.

[0045] It should be noted that during the carbonization and modification process of the recycled coarse aggregate in the box 1, carbon dioxide is introduced through the air inlet pipe, passes through the interior of the cylinder 201, the air inlet hole, and the connecting channel 5, and is ejected from the nozzle. During the stirring process of the recycled coarse aggregate, the carbon dioxide can be fully dispersed, so that the carbonization reaction of the recycled coarse aggregate is sufficient, which can shorten the time required for the preparation of the carbonized and modified recycled coarse aggregate and improve the preparation efficiency.

[0046] Specifically, the fifth gear 29 is driven by the first motor to rotate. The rotation of the fifth gear 29 can drive the annular rack 30 and the fourth gear 28 to rotate, and then drive the third gear 27 to rotate. The rotating column 2 rotates as the third gear 27 rotates, and then the mixing column 4 stirs the recycled coarse aggregate. The rotating drum 31 rotates together with the annular rack 30, and the cylinder 203 cooperates with the second annular groove to drive the rotating column 2 to move up and down.

[0047] A lifting block 2031 is fixedly connected to the middle of the surface of the cylinder 203, and columns are symmetrically slidably connected inside the lifting block 2031. Both columns are slidably connected to the lifting block 2031, and the lower ends of the two columns are fixedly connected to the top of the box body 1;

[0048] It should be noted that the arrangement of the lifting block 2031 and the column can limit the installation of the cylinder 203, so that the rotation of the drum 31 can stably drive the rotating column 2 to move up and down.

[0049] The surface of the rotating column 2 is provided with annular evenly distributed limiting grooves between the horizontal column 3 and the cylinder 201, and the plurality of limiting grooves are all slidably connected to the third gear 27;

[0050] It should be noted that the setting of the limiting groove can ensure that the third gear 27 rotates stably to drive the rotating column 2 to rotate, thereby playing a limiting role.

[0051] The adjusting mechanism 26 includes a rotating sleeve 261 fixedly connected to the bottom of the second gear 25. The rotating sleeve 261 is rotatably connected to the top of the water tank 20. A pressure plate 262 is slidably connected to the inner wall of the water tank 20. A fixing column 263 is fixedly connected to the upper surface of the pressure plate 262. A spiral groove 264 is formed on the outer side of the fixing column 263. A protrusion 265 is mounted on the end of the spiral groove 264 near the pressure plate 262. The protrusion 265 is fixedly connected to the inner wall of the rotating sleeve 261. An exhaust hole 266 is formed in the middle of the surface of the pressure plate 262. A cover is installed below the exhaust hole 266 via a torsion spring. A water outlet is formed on the end of the surface of the water tank 20 near the bottom, and the water outlet is connected to the second connecting pipe 19.

[0052] It should be noted that the regulating mechanism 26 can play a regulating role, so that the water in the water storage tank 20 can enter the interior of the box body 1 through the second nozzle 14, and clean the parts of the surfaces of the rotating column 2 and the stirring column 4 that are in contact with the recycled coarse aggregate. According to actual production conditions, after the carbonization modification of recycled coarse aggregate of one material is completed, it can be cleaned in time, and then the next recycled coarse aggregate of a different material can be quickly replaced for carbonization modification, thereby improving the preparation efficiency;

[0053] Specifically, under the action of the first spring, the boss 17 moves as the rotating ring 12 rotates. The boss 17 contacts the rotating plate 22, driving the vertical column 21 and the first rack 23 to move. The movement of the first rack 23 drives the first gear 24 to rotate, and then drives the second gear 25 to rotate. The rotating sleeve 261 rotates as the second gear 25 rotates, and the protrusion 265 cooperates with the spiral groove 264 to drive the fixed column 263 to move downward, so that the water in the water tank 20 can pass through the second connecting pipe 19 and the first connecting pipe 18. The second nozzle 14 sprays to clean the surface of the stirring column 4 and the rotating column 2 inside the box body 1. In the process of the pressure plate 262 moving away from the top of the water tank 20, the cover is in close contact with the exhaust hole 266 to ensure that water can be discharged stably from the water tank 20. In the process of the pressure plate 262 moving toward the top of the water tank 20, the cover can be opened to allow air to enter the inside of the water tank 20, ensuring that the water in the water tank 20 can be discharged again when the pressure plate 262 moves away from the top of the water tank 20 next time.

[0054] An annular block 32 is fixedly connected to the top surface of the water tank 20 near the edge. A movable column 8 is slidably connected to the inner side of the annular block 32. The end of the movable column 8 away from the annular block 32 is fixedly connected to the first rack 23. A second spring is sleeved on the outer side of the movable column 8.

[0055] It should be noted that when the first rack 23 is adjusted to move in the direction of compressing the second spring, relative movement can occur between the annular block 32 and the movable column 8. After the boss 17 is separated from the rotating plate 22, under the elastic force of the second spring, the first rack 23 can be restored to its initial state, so as to facilitate the reset of the first rack 23 after being adjusted. During the movement of the first rack 23, the first gear 24 rotates as the first rack 23 moves, the second gear 25 rotates as the first gear 24 rotates, and the rotating sleeve 261 rotates as the second gear 25 rotates, thereby being able to adjust the pressure plate 262 and the fixed column 263 to reset.

[0056] It should be noted that a circular hole may be provided on the top of the water tank 20 for air to enter and exit the water tank 20, and a discharge valve may be installed on the surface of the discharge port to control the discharge of recycled coarse aggregate in the box body 1. A controller may be installed on the upper surface of the top of the box body 1 next to the first motor. The first motor and the discharge valve are both electrically connected to the controller, and the controller is controlled by a computer.
